RE:
Yes we do have history texts. The last "Global War" was about 50 years ago, when the Spanish tried to reclaim their glory days by reinvading parts of Europe they dominated back in the 16th century of the Christian calendar. They and their Manchu and Persian allies were stopped by a united front of Cabotia, the United Kingdoms of Bharat, the Russian Empire, France, Corea, the Egyptian Empire and the Xianjin Dynasty (among others).
This was followed by the Atomic War, when the Russians and Xianjin devasted each other fighting over the partitioned parts of Manchuria. After that, the Congress of Nations and the International Brigades were formed (Cabotia and Bharat being the two largest contributors to both of these).
